Subject: Re: Frame-relay BW statement question

This does not look right to me.

To my knowledge, there is nothing in IOS that connects clock rate to an
IOS displayed bandwidth statement.

Could you post the device configs and the unedited show command outputs?

On my routers I have a clock rate defined of 72000, however my show
commands display the following:

R1#sho fram map
Serial0/0.12 (up): point-to-point dlci, dlci 102(0x66,0x1860), broadcast
          status defined, active
R1#sho int s0/0.12
Serial0/0.12 is up, line protocol is up
  Hardware is PowerQUICC Serial
  Internet address is 12.12.12.1/24
  MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec,
     reliability 255/255, txload 1/255, rxload 1/255
  Encapsulation FRAME-RELAY
  Last clearing of "show interface" counters never

Group - I have a frame relay question..... on the following show frame
map, it shows BW=256000. The documentation is a bit silent on this
issue, but is this determined by the cir of the line, or, the clock
speed that the interface is receiving. There is no bandwidth statement
configured. TIA.
